As ice melts, Everest's 'death zone' gives up its ghosts

Among those scaling the soaring Himalayan this year was a team not aiming for the 8,849-meter (29,032-foot) peak, but risking their own lives to bring some of the corpses down.

Five as yet unnamed frozen bodies were retrieved—including one that was just —as part of Nepal's mountain clean-up campaign on Everest and adjoining peaks Lhotse and Nuptse.

It is a grim, tough and dangerous task.

Rescuers took hours to chip away the ice with axes, with the team sometimes using boiling water to release its frozen grip.

"Because of the effects of global warming, (the bodies and trash) are becoming more visible as the thins," said Aditya Karki, a major in Nepal's army, who led the team of 12 military personnel and 18 climbers.

More than 300 people have perished on the mountain since expeditions started in the 1920s, eight this season alone.

Many bodies remain. Some are hidden by snow or swallowed down deep crevasses.

Nepalese army personnel move frozen corpses retrieved from Everest into an ambulance for their eventual cremation.

Worker segregate waste materials retrieved from Mount Everest for recycling.

The thin air and low oxygen levels of Everest's 'death zone' make recovering bodies a dangerous business.

A clean-up campaign employing guides and porters has cleared 11 tonnes of rubbish from Everest.
